Abstract The distributed-microstructure model for the flow of single phase
fluid in a partially fissured composite medium due to Douglas-Peszyńska-Showalter [12] is extended to a quasi-linear version. This model contains the
geometry of the local cells distributed throughout the medium, the flux exchange
across their intricate interface with the imbedded fissure system, and
the secondary flux resulting from diffusion paths within the matrix. Both the
exact but highly singular micro-model and the macro-model are shown to be
well-posed, and it is proved that the solution of the micro-model is two-scale
convergent to that of the macro-model as the spatial parameter goes to zero.
In the linear case, the effective coefficients are obtained by a partial decoupling
of the homogenized system.
